Oregon’s estate tax reaches further than many people expect. While many residents are familiar with the federal estate tax, which in 2026 applies to estates above $15 million, Oregon’s threshold sits at just $1 million, a figure that hasn’t changed in years and isn’t adjusted for inflation.
For families who own a home, hold retirement savings, or have invested over a lifetime, crossing that threshold may be more likely than they realize. Understanding how Oregon’s estate tax works, and who it applies to, is a meaningful first step toward protecting the assets you’ve worked hard to build.
How Oregon’s estate tax works
Oregon imposes a graduated estate tax on estates valued at $1 million or more. The tax rate ranges from 10% to 16%, depending on the size of the taxable estate.
An often-overlooked feature of Oregon’s tax framework is that it calculates the estate tax on the full value of the estate, including out-of-state assets, and then applies a fractional formula based on the proportion of Oregon-located property. This means out-of-state property can increase the effective tax rate even when it isn’t directly subject to Oregon tax.
Residents vs. non-residents: a critical distinction
Oregon’s estate tax doesn’t apply only to state residents. Non-residents who own Oregon property may also have a tax obligation, and the rules differ meaningfully between the two groups.
For residents, the tax applies to all intangible assets such as bank accounts, stocks, and Limited Liability Company interests, regardless of where those assets are located, as well as to Oregon real estate and tangible personal property. Out-of-state real estate is excluded from the Oregon taxable portion but is still counted when calculating the overall estate value.
For non-residents, the tax applies only to Oregon real estate and Oregon tangible personal property. Intangible assets are not taxed. This distinction creates an important planning opportunity: by restructuring how Oregon property is held, non-residents may reduce or limit their Oregon estate tax exposure.
Unlike the federal estate tax, Oregon does not offer portability, meaning a surviving spouse cannot use the deceased spouse’s unused exemption. Each spouse’s $1 million exemption must be planned for separately.
| Oregon residents | Non-residents | |
|---|---|---|
| Bank accounts & stocks (intangibles) | Taxed, regardless of where held | Not taxed |
| LLC interests | Taxed | Not taxed |
| Oregon real estate | Taxed | Taxed |
| Oregon tangible personal property | Taxed | Taxed |
| Out-of-state real estate | Excluded from taxable portion — but counted in overall estate value | Not taxed |
| Key planning opportunity | Use credit shelter trust to preserve both spouses’ $1M exemptions | Hold Oregon real estate in an LLC to convert it to non-taxable intangible property |
The federal-Oregon gap in 2026
The 2026 federal estate tax exemption rose to $15 million per individual, while Oregon’s exemption remains at $1 million with no inflation adjustment. This growing gap means that many families who owe nothing at the federal level may still face a meaningful Oregon estate tax bill. Proactive planning, rather than a last-minute review, tends to offer more options and greater flexibility.
For those whose estates do cross the $1 million threshold, the tax can be significant and a family with a home, retirement savings, and life insurance coverage can quickly approach that threshold.
Five strategies worth considering
Estate planning involves no one-size-fits-all answer. That said, several strategies are well-suited to addressing Oregon estate tax exposure across a range of financial situations.
1. Use a credit-shelter trust to maximize both spouses’ exemptions
Because Oregon does not allow portability, married couples may find it valuable to establish a credit shelter trust, also called a bypass trust, in their estate plan. By directing the assets of the first spouse to pass up to the $1 million exemption, the couple could preserve both individual exemptions, potentially shielding up to $2 million from Oregon estate tax. This approach requires coordination with an estate planning attorney and may need to be updated as circumstances change.
2. Take advantage of Oregon’s no-gift-tax environment
Oregon does not impose a state gift tax. This creates an opportunity for lifetime gifting as a strategy to reduce the size of a taxable estate. Gifts made during one’s lifetime can also remove assets, and their future appreciation, from the estate.
3. Review how Oregon real estate is held
For non-residents who own Oregon real estate — whether a vacation home or rental or investment property — holding that property in a limited liability company (LLC) may convert what would otherwise be taxable real property into non-taxable intangible property. This is because LLC ownership interests are generally treated as intangible assets, which are not subject to Oregon estate tax for non-residents. This strategy involves legal and tax considerations that should be reviewed carefully by qualified advisors before implementation.
4. Plan for liquidity
Oregon estate tax is due nine months after the date of death.1 Many estates, particularly those that include illiquid assets such as real estate, a family business, or investment holdings, may face a cash-flow challenge when the tax bill comes due. Planning for liquidity in advance, whether through life insurance held in an irrevocable trust, a systematic gifting program, or other approaches, may help the estate meet its obligations without requiring a forced sale of assets.
5. Coordinate charitable giving with estate planning
For clients with philanthropic goals, charitable giving can serve a dual purpose:
- Supporting causes that matter to them
- Reducing the taxable estate
Options such as donor-advised funds, charitable remainder trusts, and direct gifts to qualified organizations may help reduce Oregon estate tax exposure while reflecting their values and legacy intentions. These strategies can be especially meaningful for clients looking to create a lasting impact across generations.
Taking the next step
Oregon’s estate tax framework is nuanced, and the interaction between state and federal rules adds complexity that changes over time. Whether you’re a longtime Oregon resident, a non-resident with a vacation property on the Oregon coast, or someone who has recently moved to or from the state, understanding your potential exposure is a valuable first step.

-
Yes. Oregon imposes a state estate tax on estates valued at $1 million or more at the time of death.

No. Unlike the federal estate tax, Oregon does not allow a surviving spouse to use the deceased spouse’s unused exemption. Each spouse’s $1 million exemption must be planned for individually.

-
Oregon uses a graduated rate schedule ranging from 10% to 16%, applied to the taxable estate — the amount above the $1 million exemption.
